Characters

The protagonist of the story. Jack becomes the only person aware of an invasion of aliens known as Body Squeezers. As the rest of the town becomes possessed by the aliens, he ends up the last human left.

A large green alien with oval eyes, deep nostrils and a small, lipless mouth. It squeezes its victims in a tight hug, then enters their body. Once the Squeezer is inside, the possessed being speaks with a weird "t-t-t" stutter. They continue to spread the possession with each person they hug.

Ted Liss

Mr. Liss is Jack's science teacher. He becomes the first person to be possessed by the Body Squeezers.

Mr. and Mrs. Archer

Jack and Billie's parents. Jack's father works for the deputy mayor. Despite his attempts, they never believe Jack about the Body Squeezers. Much like most of the town, they too become possessed.
